Answer:
Alkene A is more stable than alkene B
Explanation:
Complete question:
The same alkane is obtained from the catalytic hydrogenation of both alkene A and alkene B. The heat of hydrogenation of alkene A is 29.8 kcal/mol, and the heat of hydrogenation of alkene B is 31.4 kcal/mol. Which alkene is more stable ?
Step 1: Data given
The heat of hydrogenation of alkene A is 29.8 kcal/mol
The heat of hydrogenation of alkene B is 31.4 kcal/mol
Step 2: Which alkene is more stable
The smaller the heat of hydrogenation, the more stable the alkene. This because it releases less heat, and has less energy.
29.8 < 31.4
This means alkene A has a smaller heat of hydrogenation than alkene B
Alkene A is more stable than alkene B
Answer:
<span>When identical particles pack in a simple cubic lattice, there is ONE particle per unit cell.
Explanation:
As we know that simple cube has eight corners and each particle at every corner is shared by eight cubic crystals. So it means that only </span><span>eighth </span>part of a particle is present at one corner of each cube. Therefore, each corner contain 1/8 particle, then all corners will contain 1/8 × 8 = 1 particle.

Answer:
J. the growth of trees
Explanation:
The growth of trees would be greatly impaired if the energy from the sun were stopped.
Plants generally use the energy from the sun to obtain their nourishment. This same process makes food available in the ecosystem.
- Plants are producers of food.
- The process of photosynthesis allows plants to manufacture food by using sunlight to drive the reaction between carbon dioxide and water to produce glucose and oxygen gas.
- The glucose is used by plant for nourishment.
